Water Regulations – What are they?

The current Water Regulations came into force on 1st July 1999 in England and Wales. In Scotland, the Byelaws 2000 are technically identical. The Regulations are property of the government and are law.

The Regulations are in place to prevent waste, misuse, undue consumption, the erroneous measurement and contamination of water.
As manufacturers of Backflow Prevention devices, we are primarily concerned with contamination.

Many water fittings are at risk of backflow protection – but it’s the use of the water that determines the level of protection that you’ll need.
Some examples are listed below.

Hose Union TapsDomestic House Gardens and similar applications are Fluid Category 3, whereas all commercial Hose Union Taps by default are Fluid Category 5.
The Water Authorities adopt a Risk Assessment Based Approach to this – and can downgrade if the application is deemed to pose less of a risk.

Clothes & Dish-washing
Domestic washers are classed as Fluid Category 3 due to the soaps and powders used. The items being washed in a domestic setting aren’t deemed to pose any significant or serious health hazard.
Washers used in non-house applications such as hotels, restaurants and high street launderettes would class as Fluid Category 4.
Further to this, washers used in Health Care Applications – such as Nursing Homes, and Veterinary Practices are deemed to be Fluid Category 5.

Bathrooms
There are Water Fittings in the bathroom that also require backflow protection.
Bidets with submersible hoses pose the highest risk and need Fluid Category 5 protection.
Showers with submersible hoses also need protection. In a domestic situation – the risk is Fluid Category 3. However, in a health care setting, this risk is deemed to be Fluid Category 5.

These examples show that it is the use, not the type of fitting that determines the what level of protection required. If in doubt, always check with the relevant water company.
